I've decided I'm going to leave AT&T and switch to T-Mobile and I'm gonna go ahead and purchase a iPhone SE in the process, so I'm trying to weigh my options of how to do so. If I do it on the T-Mobile website, it looks like I'm going to be charged a $25 "Sim Kit" which is basically masquerading as an activation fee. On top of that I'll have to wait 2 to 4 days for the phone to be shipped to me unless I want to pay extra for overnight shipping. If I call up T-Mobile directly, I can probably get them to swing overnight shipping for me for free, but the activation fee/sim kit may be a harder sell, if at all. But what's the deal with buying it from Apple? I see the website says a T-Mobile SIM is included and that I'll have to go into the store to switch carriers, but if I do so, do they charge the same $25 that T-Mobile would or do they activate the phone for free?
